SN74ABT125NE4

具有三态输出翻两番总线缓冲器GATES QUADRUPLE BUS BUFFER GATES WITH 3-STATE OUTPUTS

description/ordering information

The ’ABT125 quadruple bus buffer gates feature independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable OE input is high.

These devices are fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioffcircuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.
